Equilibrium:Le Chatelier’s principle Le Chatelier’s principle describes how a system atequilibrium reacts to changes (stresses) in system conditions. It states that if a system at equilibrium is disturbed by a change in temperature, pressure, or one of the components concentration, the system will transfer its equilibrium place to counteract the outcome of the disturbance. In … Read more
Equilibrium: Factors affecting the equilibrium The equilibrium of a system shift to a new position in order to minimize any changes due to the alteration of certain factors that influence the equilibrium. To determine which factors, affect the rate, it is important to determine what happens during a chemical reaction. In a chemical reaction, the … Read more
Equilibrium: Equilibrium constant The equilibrium constant (K) is a number that represents the concentrations of reactants and products of a reversible reaction at a given temperature K = [products]/[reactants] For a general chemical equation The equilibrium constant is written as Where: Small superscript letters are the stoichiometry coefficients [A] is the concentration chemical species where … Read more
Equilibrium: Law of mass action The Law of Mass Action states that the equilibrium expression depends on the equilibrium concentrations of reactants and products. When a reactive system comes to equilibrium at a given temperature, the value of equilibrium constant is always the same even when all concentrations are different. This constant value of equilibrium … Read more
With the industrial revolution, the world had been through great changes ascending towards the 21st century. This is the age of advanced science and technology that has answers to probably anything. With all these changes in the queue, the level of industrial pollution has also been noted to be continuously increasing. What is industrial pollution? … Read more
Smog word is derived from fog and smoke. The most common form of air pollution is Smog which has its appearance in so many cities across the globe. As you know that smog is usually in dense or urban areas and huge population regions. With any kind of atmospheric pollution, disregarding its composition, source, … Read more
In the atmosphere, the molecules which are present are constantly colliding and moving with each other, as illustrated by “Kinetic-Molecular Theory”. During the daytime, also the atmosphere is constantly lit up. As a consequence, light energy absorption held by the molecules of atmosphere can generate “photochemical reactions.” Such reactions don’t appear at regular atmospheric … Read more
The temperature of the earth’s surface is noted to be increasing continually since the year 2000 with increasing issues of global warming. What is Greenhouse Effect? Carbon Dioxide which is one of the major constituents in the atmosphere has several important roles to play. It absorbs the infrared radiations in the atmosphere and also … Read more
Every single environmental element has a specific role to play and complete several important reaction cycles. The destruction of any of these elements could create major imbalances. Ozone Layer Depletion The ozone layer that prevails in the stratosphere is known to act like a protective shield for the earth against the harmful ultraviolet rays … Read more
According to the Modern Periodic Table, there are total 118 elements present in it and are known to mankind. 24 elements out of 118 are prepared synthetically whereas the remaining elements have natural occurrence. A few of the elements were discovered formerly and some more elements are recently discovered by the team work lead … Read more
